Upgrading Istio

I have an issue with upgrading istio. First of all, I am running my current version on 1.12.2. I couldn’t upgrade to 1.13.2. It takes me directly to 1.16.2 and after the upgrade, I do not see the istiod and other components when I run Istioctl proxy-status.

Secondly, my sidecars are not syncing with the new istiod after modifying the namespace to istio.io/rev: 1.16.2. Not sure what’s going on
